Our Raw Materials

Our products line covers all kinds of alloyed materials and specifications which are widely used in heat exchangers including automobile HVAC system such as radiator, condenser, evaporator, heater, oil cooler, and charge air cooler as well as construction machinery & equipment cooling systems, power station cooling system, micro-channel cooler and all kinds of both commercial and residential air-conditioners as well as heating and cooling systems.




In heat exchangers such as those used in air conditioning systems, the surface area available for heat transfer is a major determinant of efficiency. One of the ways air conditioner manufacturers meet enhanced energy efficiency standards is by using significantly greater quantities of finstock.

Drawn/Extruded Tube

Aluminum tube is designated as “extruded tube” or “drawn tube”, while drawn tubes are more popular in many applications. Drawn tube obtains its mechanical properties and dimensions by drawing “extruded tube” through a die. In addition to adding strength, the drawing process provides exceptional dimensional control and a superior surface finish that would not be attainable in an extruded tube of the same alloy and size. Drawing also enhances the bending, flaring and formability of tube.

Aluminum tube is also recognized as seamless tube & porthole tube per different extruding process.

Tubes are sold in two configurations: coil and straight lengths.

Micro-Multiport Extrusion Tube

Micro-Multiport Extrusion Tube (MPE Tube) is mainly used for the production of heat exchangers. Due to its high corrosion-resistance & good heat conductivity, MPE tube is particularly well suited for the use in evaporators & condensers with refrigerant R134-A. To meet the market requirement, Ravimex International can supply zinc-coated & flux coated MPE tubes, it can be supplied in coils, or fixed length by non-cutting separation method.

Alloy: 1100, 1050, 3003, 3102, etc.
Temper: H112
Common sizes: 18X1.2, 18X2.2 & 15X2 and so on
Application: Condenser, evaporator



The Level Wound Coil (LWC)

The Level Wound Coil (LWC) Copper Tube is applied to air conditioning, refrigeration as well as heat exchanger fields. It is produced most commonly in soft and light annealed form but can also be ordered in hard drawn temper.

All LWC tubes are normally produced according to ASTM & Coproclima specifications. These specifications are prepared to take account of the requirements of ACR industry.

For heavy coils, we wound LWC copper tubes in “Eye to Sky” (Jumbo) form as per customer request. The tube is cleaned with Nitrogen purging. Moreover to protect the tubes against dust & internal oxidation during transportation or long storing, the tube ends are sealed with plastic caps and delivered with cardboard reels. Coils on reels are stacked on wooden pallets and shrink wrapped.

Specification:  O.D: 3/16″ to 3/4″ (4.76 to 19.05 mm)
Coil Weight:100- 400 Kg
Application: Applied to the air conditioners, assembly-type air conditioning units, refrigerators, freezers, chests, etc.

Production range for LWC copper tubes:

*Tip: Row line=W.T and Column Line=O.D


Note: Other sizes can be made as per customer’s requirement according to mutual agreement.


Pancake Copper Tube (PCC)

Pancake Coil Copper Tube (PCC) is mainly applied to air conditioning and refrigeration industry and installation. According the EN standard the Pancake tube has good bending properties for usage in utility supplies such as plumbing installations, gas transport networks, air conditioning systems and refrigerant piping.

Our Pancake tube fulfills the requirements according to the American Society for Testing and Materials Standard Specification B280 and EN12735 and other general norms for refrigeration tubes. These products are supplied in the annealed form. All coils are cleaned and capped to keep contaminants from entering the tube. Then they are individually labeled, shrink wrapped and boxed in cardboard cartons for ease of handling and distribution.

Specification: O.D.: 1/4″ to 7/8″(6.35 to 22.22 mm)
Coil Length:50′ to 180′ (and/or 15 to 55 meter)
Application: Mainly applied to air conditioning units

Production range for Pancake copper tubes:

*Tip:Row line=W.T and Column Line=O.D


Note: Other sizes can be made as per customer’s requirement according to mutual agreement.



Aluminum Tape

Aluminum tape, also known as foil tape, has many uses in the electrical, HVAC and construction industry. It can be used in jobs requiring moisture and chemical resistance, thermal conductivity, flame resistance, heat and light reflectance, and weatherability. There are several different styles of tape available, including acrylic adhesive, line-less, polymer coated, and flame resistant aluminum glass tape.

Foil tape with an acrylic adhesive is used for sealing off vapors in fiberglass duct board, sheet metal ducts and FSK systems. It is ideal for use in HVAC systems, due to its high tack cold weather acrylic adhesive, which helps it to adhere well, even in periods of low temperature and high humidity. It performs at its optimum level in temperatures between -4.4°C and 121.1°C, with a tensile strength of 9.5 kg per 2.54 cm of width.
